Investigation of Key Automated Vehicle Human Factors Safety Issues Related to Infrastructure

  • April 8th, 2025

This study examined the degree to which an in-vehicle signal countdown timer influenced human drivers’ intersection approaching behaviors and decisionmaking. Secondarily, the study compared intersection approaching behaviors between human drivers and automated shuttles. The research team further simulated predicted behaviors of human drivers at lower speeds and predicted behaviors of shuttles at higher speeds. The […]

Formal Recommendations of the Transforming Transportation Advisory Committee to the US Department of Transportation on Artificial Intelligence, Automated Driving, Project Delivery, and Innovation for Safety

  • February 7th, 2025

This report formally presents TTAC’s recommendations to USDOT on these four topics. Although transportation encompasses more than walking, biking, driving, and riding, the Committee’s primary expertise and hence its advice center on surface transportation. Several key themes cut across TTAC’s recommendations. Read the full study here.

Identifying Outcome Measures to Evaluate Drivers’ Knowledge of Vehicle Automation

  • November 25th, 2024

Advanced vehicle technologies have the potential to improve safety and convenience for drivers; however, to realize these benefits, it is important that drivers use the systems appropriately. Past research has documented gaps in drivers’ understanding of how new technology works and when it should be used. It follows that the interplay between a driver’s knowledge, […]

A Multi-Method Approach to Understanding Drivers’ Experiences and Behavior Under Partial Vehicle Automation

  • October 9th, 2023

Automated vehicles have the potential to improve safety and mobility. At lower levels of automation (Level 2), drivers are required to supervise the automation and be prepared to intervene as needed to maintain safety. The consequences of these technologies on driver behavior are not yet fully understood, especially as real-world testing has been less common […]

Examining the Safety Benefits of Partial Vehicle Automation Technologies in an Uncertain Future

  • September 22nd, 2023

Emerging vehicle technologies have the potential to make driving not only more comfortable but also safer. Many motor vehicle crashes result from mistakes made by drivers. Advanced driver assistance systems (ADAS), common in today’s new vehicles, have the ability to warn the driver or even intervene automatically in many situations to help the driver avoid […]

Measuring and Predicting Drivers’ Takeover Readiness and Supporting Takeover Transitions in Automated Driving

  • September 19th, 2023

As vehicle automation takes on more and more of the driving tasks, the driver’s role will transform from an operator to a system supervisor. With higher levels of automation, the automated vehicle is able to monitor the environment, allowing the driver to engage in non-driving related tasks. However, if the automated vehicle reaches its system […]

Examining the Safety Benefits of Partial Vehicle Automation Technologies in an Uncertain Future

  • August 21st, 2023

Advanced driver assistance systems (ADAS) are designed to increase driving comfort by automating parts of the driving task under certain conditions, as well as increase safety by warning drivers of dangerous situations and momentarily braking or steering automatically to attempt to avoid crashing. These technologies have become common on new vehicles, and they are expected […]

Human-Machine Interfaces and Vehicle Automation: The Effect of HMI Design on Driver Performance and Behavior

  • July 27th, 2023

Driving automation systems have become more widely available and popular over the past several years. While vehicle automation offers drivers both safety and convenience, automation may also have negative consequences, such as increased driver engagement in non-driving related tasks. The issue of driver inattention while using these technologies underscores the importance of systems that issue […]
